Tapping head with cartridges and integrated lub nozzles

In order to meet your needs, we have designed a range of tapping units based on a tapping head in which it is possible to add several functions such as vertical strip following, quick approach, strip guiding and strip piloting. Each function can be used with a mechanical or a servo-driven motorization.

TKS - VERTICAL STRIP FOLLOW AND STRIP GUIDING

TKD - QUICK APPROACH AND STRIP PILOTING

The strip following function (pressure pad) enables the tapping head to follow the vertical movement of the strip while reducing the room taken by the tapping station.

• Pressure pad integrated to the tapping unit: Simplification of the work of the toolmaker and the designer. Simpler, shorter dies.

•Strip following function:Integration of the pressure pad function to the quick installation kit of the tapping unit. Simplified, more compact tapping station.

• Strip guiding function: No unplanned movement of the strip at the tapping stage. The strip moves without any problem.

In case of a complex application (very large or complex strip), the “rapid approach”, driven by a cam, brings the tapping head to the strip just after the end of the strip feeding.

•Pressure pad integrated to the tapping unit: Simplification of the work of the toolmaker and the designer.

• Quick approach: Optimized tap travel. Kinematics

perfectly optimized.

• Piloting (option): Positioning and clamping of the strip before the beginning of the tapping operation in order to avoid foreign stress on the tap.

TK - PHILOSOPHY

The «TKN» tapping units replace the «Mx» tapping units.The tapping station is made by the toolmaker.

• Lightened head: easy handling.•Cartridge with a system that can

CARTRIDGE TECHNOLOGYSynchronized tapping: Guarantee of

high-quality threads Most PRONIC tapping units use this system consisting of a tapped template gear and a threaded tap holder. This assembly is called a cartridge.

These two components have exactly the same thread pitch as the tap. When the cartridge moves by one pitch, it drives the tap to move one pitch. Therefore we can talk about synchronized driving of the tap: it is a current control over the position of the tap throughout the whole tapping cycle.

The cartridge is secured:• In case of overload or when there is no hole to tap, the template

gear unclutches to prevent tap breakage.•Thetemplategearclutchesagainautomaticallyattheendofpresscycle

with the tap back in its original position.• The cartridge is designed with an axial and radial clearance to absorb

unwanted strip movements.•The waterproofness of the cartridge has been reinforced for a longer life.

Thanks to this system we can guarantee that:• theprocessofformingthethreadsis100%accurateandreliable,and• 100% of the parts are thread-formed (see also the description of the

DETECv2 system under “PRONIC accessories”).

Minimal thread pitch 0,50 0,15

Minimal center distance

from32,5mm* from10mm*

Number of spindles from 1 to ... from 1 to 6

* Depends on tap dimension

In some cases we choose to offer a solution with a guided tap system which is based on our patented planetary gear technology.

The planetary gear can support one or multiple spindles at the same time.The synchronic movement of the spindles' rotation and translation of the planetary gear is generated by a specific gear.This combination creates perfectly synchronic screw motion.

This technology has the same advantages as the cartridge technology, and at the same time enables tapping with smaller distance centers, as well as fine

thread pitches. It is also recommended for high speed stamping.

PLANETARY GEAR TECHNOLOGY

A SYNCHRONIZED TAP DRIVING...IS A GOOD QUALITY TAPPING

Every tapping solution recommended by PRONIC uses a 100% mechanically guided tap system.

Tap movement is managed throughout the whole tapping operation:

• Secured tapping

• Endurance and reliability

CARTRIDGE TECHNOLOGY MECHANICAL MOTORIZATION Tapping to the rythm of your press

The motorization, fastened on the lower shoe and lubricated by a bath of oil, transforms the linear motion of the press ram into a rotation movement inside the tapping head.

The motorization is equipped with a grooved shaft which allows the tapping head to follow the vertical movement of the strip.

This configuration enables you to make a simple and economic tool.

These motorizations are universal and can be used in several tools. The quick installation kit delivered with the transmission allows for quick die change and facilitates maintenance.

The position of the motorization is locked with an indexing pin.

Ø16 Transmission

Ø25 Transmission

Max Press stroke upto300mm up to 500mm

Max Strip lift up to 45mm up to 90mm

Tapping independently from the rythm of your

pressThe PRONIC servo-driven tapping units (offered since 1994) are made with most components used on the mechanical units.

Here, the mechanical motorization is simply replaced by a high dynamics servomotor which is piloted by our PRONIC PRC M400 controller, with color touch screen, that:

• enables a single connection to the press,• iscapableofpiloting up to 4 motors,• manages all of the PRONIC peripheral items as well as sensors and

actuators (cylinders…) of the tapping station,• manages electrically the torque of the motor, and• guarantees that 100% of the parts are tapped if the controller is

associated with a tap detection system.

With its independance from the press stroke, this solution is particularly interesting for applications with long press strokes or, alternately, applications with very short press strokes.

These units are particularly adapted to work with transfer dies, fine-blanking and multi slide applications. You can also find them as module base equipment for PRONIC in-line machines or as stand alone machines.

TURNKEY SOLUTIONS...THE CUSTOM TAPPING STATIONS

WHY CHOOSING A TAPPING STATION ?

ENVIRONMENT OF THE APPLICATIONS

DIFFERENT TYPES OF TAPPING STATIONS

PRONIC can recommend complete machines for your tapping operation built in accordance to your specifications and production requirements.

In doing so, we take the responsibility for the application functions regarding the tapping process, and offer you a turnkey solution optimizing the production capability as well as its efficiency.

In this way, you take full advantage of PRONIC’s experience and reduce the time needed for designing and building the tool, and at the same time you can count on receiving the most effective solution.

After reviewing the configuration and size of your machine/die and your specifications, PRONIC can recommend an appropriate tapping-module:

• “Cassette” type (Pic 1): a plug-and-play solution where we deliver the complete tapping module/cassette that easily slides into your die.This type of construction has a top and bottom basic plate with pillars and offers a complete tapping station, making it a perfect option retrofiting an existing die.

• ”Solid Mounting and/or Reverse Mounting” type (Pic 2) (tapping from bottom to top): This option is used in transfer dies, for example.

• “Pressure Pad” type (Pic 3): we deliver the tapping station, which must be integrated into the toolings.Top and bottom plates are not provided in this option.

PRONIC designs and builds the complete tapping station in close cooperation with the builder of the tool and the customer’s design office. All functions and elements necessary for the process of tapping are “on board” for the PRONIC slide subunit tapping module: it is ready for “turnkey” operation.

Our tapping units work mainly on progressive dies and transfer dies.

Today we are also able to offer custom-built modules, for such applications in fine-blanking, multi-slide, or stand alone applications.

Our complete product line of tapping units may be used to meet the design requirements of your tooling (for placement, required safety functions, etc.).

Because the lifetime of the tap depends on the effectiveness of its lubrication, PRONIC developed the micro-lubrication system specifically to coordinate the tapping process.The system is compact, environmentally friendly, efficient and guarantees a significant savings due to metered application of the tap lubricant.

Principle:Micro pumps push the oil into the nozzles, where the air flow turns the oil into micro droplets which are sprayed directly onto the surface of the tap.Depending on the intensity of the tapping process, the amount of oil and the spraying pulse frequency can each be adjusted.Oil consumption is so light that an expensive recovery is unnecessary.

PRONIC micro lubrication system is composed of pump modules which can be expanded for upgrade as necessary. You select the number of points for lubrication and the size of the the lubricant reservoirthatyouprefer(3,7lor6lreservoirsareavailable).

DETEC completes the PRONIC tapping solution by ensuring total control of the tapping process during your production. Simplifying your die design, this highly reliable device can easily be integrated in your future dies and/or your existing ones. DETEC monitors closely the accuracy of your tapping operation, eliminating the need to sort your parts out because of broken taps, a pre-hole too small,

or a miss feed.

Principle:Despite the fact that the structure of DETEC is fully mechanical, it is able to sense the smallest physical movements at the bottom of the tap stroke.

To begin, the mechanical signal is transferred through a shielded cable to the adjusting nut on the receptor, fastened outside the tool where it activates the proximity switch.

The proximity switch is connected to the press. If the tap does not penetrate the part and depress the tap sensor, the press will stop immediately.

To answer the need for cost and process reduction, PRONIC created machines for in-line tapping.

Loading of the machine is fully automatic and directly connected to the output of the press.

The parts may be transferred in different ways:• in one course from tool production, or• the parts stay on the conveyor belt and in this case the final

station and/or escapement is installed on the machine.

The cycle is fully automated from the conveyor belt to the tapped part.

Finished parts leave the tapping machine.

For several years PRONIC has been offering application-specific tapping machines for high volume production and/or high speed stamping.

The benefits of these solutions are:• no restrictions in size of tap dimension,• no restrictions in the number of threaded holes,• no restrictions in efficiency; tapping is not the limiting production

factor any longer,• possibility to process most of the partial references on the same

machine.

Tapping is executed by a PRONIC servo-driven unit, which is equipped with one or multiple taps depending on the part and production requirements.

In order to guarantee the quality of tapping, all PRONIC machines are equipped with:

• micro lubrication system, which are also used with unit in the die, and•Tap-breakage system, as well as torque monitoring.

Thanks to these, you are guaranteed that all parts which leave our machine are really tapped.

PRONIC machines are equipped with a user interface - intuitive touch screen for the purposes of managing the work and production settings .Our machines are compliant with valid standards and specifications and are delivered with CE Certificate.

The machine adjusts to your production: it is possible to tap additional part features on the same machine thanks to quick and easy placement of the specific parameters for establishing features and the required tapping heads.

No more part output limit!

PRONIC offers tapping machines with semi-automatic loading using the same concept as in-line tapping.

Loading of the parts is executed by the semi-automatic supply system (vibrating conveyor, conveyor belt for loading, magazine ...) which will be loaded by the person operating the machine.

The machine cares for the transfer of parts by itself. As well as in the case of the in-line machine, part delivery is guaranteed by several different types of transport systems:

• indexing-table system.

• conveyor belt-transport system.

• pick-and-place system or other.

PRONIC Solution for large production

volumes, in a situation when the

machine cannot operate in-line with the press

Tapping Machines, for secondary operations using manual loading and unloading of the parts are ideal for low production volumes and for parts with many threads.

The parts are manually loaded into the machine by the operator who then initiates the tapping operation.

You can have one or multiple threads tapping, therefore, all combinations are possible.

Our secondary operation machines comply with all the safety standards and include a two-handed release mechanism as well as a safety light curtain.

These machines also use micro lubrication systems, as well as tap sensor torque monitoring. This allows us to guarantee you a perfect quality thread.

• giving practical training of the allocated staff for general maintenance and use of the equipment at your company,

• mounting the unit to the tools by comparing the real parameters with the values defined by PRONIC, and

• monitoring production until the efficiency recommended by PRONIC is obtained.
